Current news at the Accelerator Laboratory

Mikko Mankinen’s dissertation presents high-precision computer simulations to evaluate how well the volumetric modulated arc therapy is delivered. Mankinen defends on Thursday June 19, 2025.

The heaviest nucleus decaying via proton emission has been measured in the Accelerator Laboratory. Exotic nuclei of this kind are extremely challenging to study due to their short lifetimes and low production cross sections.

The work of Arthur Jaries was conducted at the Accelerator Laboratory within the IGISOL group, utilizing the JYLFTRAP double Penning trap setup to perform precision mass spectrometry of exotic neutron-rich rare-earth isotopes. Jaries defends on 5.6.2025.

During the experimental phase of Henna Joukainen’s doctoral thesis presents her study of the excited states of three isotopes – arsenic-66, tungsten-165, and tungsten-169 – and the testing of a new detector for recoil-beta tagging.

Doctoral Researcher Joona Kasurinen determined the probabilities of certain scattering events in his dissertation work. The public examination of Joona Kasurinen's dissertation is held on Friday 16.5.2025 at 12.00.

Adrian Montes Plaza combined in his doctoral thesis the results from two experiments in which Pb-190 was produced via fusion-evaporation reactions and that were conducted at the Accelerator Laboratory of the University of Jyväskylä.

Researchers at the University of Jyväskylä have discovered a potential nuclear beta decay that could be used for antineutrino mass determination. The study has been published in the highly respected Physical Review Letters.

The Department of Physics is closely integrated in the activities of the CERN research institute. The large experimental collaborations at CERN were honoured with the Breakthrough Prize in Fundamental Physics.

The University of Jyväskylä and the Finnish Radiation and Nuclear Safety Authority has developed multi-purpose radiation detector can be compared to the Swiss Army knife. A handheld radiation detector that detects almost all types of ionizing radiation.

Doctoral Researcher Andrea Raggio investigated in his dissertation thesis the development of laser and decay spectroscopy experiments and improving the production of radioactive ion beams of actinides. The doctoral dissertation will be held on 28.3.2025.

Researchers measured very precisely atomic masses of radioactive lanthanum isotopes and found an interesting feature in their nuclear binding energies. The masses for the two most exotic isotopes were measured for the first time.

A new milestone in nuclear physics has been achieved with the direct observation of three different deformations in the atomic nucleus of lead-190. The experiments were conducted at the Accelerator Laboratory.
